<p>The invention concerns a device for operating a movable covering element (10) arranged for guided displacement movements along opposite side edges between open and closed positions while being driven by a drive means (15) arranged in a space adjoining the covering element path of movement. In accordance with the invention the drive means is formed by a drive belt (13) which is arranged to travel about spaced apart deflecting members and which is connected with the covering element at spaced-apart attachment places in such a manner as to produce the covering element movements by advancing one run of the drive belt in a direction away from or towards the respective deflecting member.</p> |
